Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Evelyn Lees for Saturday - November 22, 2014 - 7:25am
bottom line

The avalanche danger will be increasing over the next 24 hours – and the rose represents the avalanche danger for late this afternoon and tonight.

  • This morning - the avalanche danger is MODERATE on steep, upper elevation, northwest, north and northeasterly facing slopes with fresh drifts of wind-blown snow.
  • This afternoon and tonight - the avalanche danger will rise to CONSIDERABLE on mid and upper elevation slopes facing west through north through east. AVOID travel on and below these slopes, as it will become possible to trigger slides from a distance and from below. Natural avalanches may be possible. In addition, avoid any of the developing wind drifts on all steep slopes.



avalanche warning

An Avalanche Warning has been issued for 3 pm this afternoon for all the mountains of northern Utah.   Dangerous avalanche conditions will develop this late this afternoon and overnight as strong winds and heavy snow overload the preexisting weak snow pack.  This Avalanche Warning is from 3 pm this afternoon through Monday. 

special announcement

While open for the season, Solitude is closed to uphill traffic. Always check with ski patrol or the main office before skiing uphill at a resort.

current conditions

This morning, the mountain temperatures are in the upper 20s to mid 30s in the Ogden area mountains. The southwesterly winds have ramped up in the past few hours – speeds across the high peaks are averaging 30s and 40s, gusting to 60 mph.. Wind speeds at the mid elevations are averaging 15 to 20 mph. The overall snowpack is very shallow – only 6 to 10” on the ground in the Odgen area mountains.

Over the past week, most of the shallow snow pack has become faceted, weak and sugary. This weak snow exists on upper elevation slopes facing west through north through east, and many of the shadier mid elevation slopes. As snow falls today and tonight, it will become possible to trigger avalanches on steep slopes and remotely from a distance. As the snow piles up, avoid slopes steeper than about 30 degrees, and travel below steep slopes.

Here is a repost of Bruce's great graphic from yesterday showing the pattern of pre-existing snow. This is for the Cottonwoods, but the Ogden area coverage is similar, just shallower.

Sensitive new wind drifts will be developing today through tonight. You will be most likely to trigger a drift where it is sitting on sugary old snow, but drifts should be avoided on all steep slopes.

weather

It will be warm and blustery this morning, with occasional light snow. The moderate southwesterly winds will gradually increase into the afternoon, and high temperatures will be in the mid to upper 30s. The cold front should arrive around 4-5 pm tonight. The strongest winds expected between 3 and 7 pm, with averages along the high ridge lines in the near 50 and gusts in the 70s. The most intense snowfall will also be around frontal passage, with rates up to 2” per hour. Estimated snowfall amounts are 3”- 6” today, with another 4” to 8” tonight. The Cottonwoods and areas favored by northwest flow could receive 4 – 7” of snow today, with 7” to 12” tonight. There should be a lull in the snow mid-day Sunday, with another shot of snow on Sunday night into Monday.
